Abstract Reinforcement particle size is very important for the performance of metal ceramic composites. This work studied influence B 4 C on mechanical properties Al matrix layered These composites were fabricated using a simplified semicontinuous casting and hot-rolling process. To obtain an optimized filling structure particles, Horsfield principle was applied to determine mass fraction particles. Four sizes particles used with various combinations. The results showed that increase fine...
A three-layered composite material, consisting of an Al outer layer and a 7075-10 wt % B4C inner layer, was fabricated by semi-continuous casting following hot rolling process. The exhibits clear layered structure with good interfacial bond between layers. In the sessile drop experiment, alloy melt dropped on 7075-B4C at 650 °C, contact angle decreasing from 105° to 25° in 50 s, indicating that infiltration spreading both played important roles wetting reinforced particles were distributed...
Al/Mg compound materials were fabricated by a solid–liquid bonding method. The well bonded interface with transition layer can be obtained. There two kinds of structures in the ingot. microstructures and properties studied. results showed that brittle was composed mainly intermetallic Al12Mg17 Al3Mg2 at top part bottom ingot respectively. reason why existed explained.
Two-dimensional carbon/carbon (2D C/C) composites are a special class of composites, generally obtained by combining resin-impregnated carbon fiber clothes, which then cured and carbonized.This study deals with the preparation protective coating for these materials.This coating, based on graphite, was prepared slurry method.The effect graphite phenolic resin powders different weight ratios examined.The results have shown that can fill pores cracks composite surface, thereby densifying...

Abstract In this paper, the effect of casting speed on fabricating Al-1%Mn and Al-10%Si alloy clad slab was investigated. Before trials with semi-continuous process were conducted, a series simulation engineering software FLUENT made to forecast influence temperature field liquid fraction slab. The results indicated that increase reduces time in cooling zone, thus thickness solidification shell under dividing plate gets thinner. Based results, successfully produced by process. interface...
Abstract In this study, fine aluminum cladding AZ91 magnesium alloy composite ingot was prepared under static casting. The microstructure and phase constituents of the interface were investigated by optical microscopy. result shows that from Al matrix side can be divided into three parts. A diffusion layer made up β-Al 3 Mg 2 , Mg-Al mtermetallic compound which is γ-Mg 17 12 a eutectic structure α-Mg . element distribution methods electron probe microanalysis (EPMA). component ratio to...
In the present study, authors used sessile drop method to simulate contacting and infiltration behavior between Al melt Al–B4C composite. order track penetration distance of metal infiltrate into Al-B4C composite matrix when is not obvious, element Si was added as tracer agent. The Al-10%Si dropped onto substrate at 913K. changes droplet bottom size, height, contact angle during spreading with surface are investigated by experiment equipment. process infiltrating can be divided two stages:...
